WA Employment Law - Forced to Resign from Mining Job

Hi I was working for a mining company FIFO for 5 years and have had a number of sleep-in violations (11 to be exact.) over my 5 years, then have procedures for sleep-in's ( such as calling before the start of shift ) and I followed them.

I've had sleep screening tests, but nothing came out of it. I then got handed a letter after I slept-in that stated I was terminated as of that date, but I had a chance to give a reason why I should stay. I know that I have one of the best safety, productive records and work great with all the personnel. But they knew that already so I took the option to resign.

Why do you feel you have been wronged? If you violated company rules or policy on numerous occasions and you received a warning and then an opportunity to provide reason why you should not be terminated it sounds as though you have been accorded due process.
